The pressure gauges should be set at 10-15 lbs. for LP units, or 4-6 lbs.. for natural gas units. (use the charts on the following pages to set pressure)

17.Press the "PROGRAM TEMPERATURE" but- ton to change the high limit set point. Press it again to change the "CYCLE SET POINT". (hi- lo units only)

18.Decrease the "CYCLE SET POINT TEM PERATURE" until the heater cycles to low flame. (hi-lo units only)

19.Open or close the low cycle ball valve until the gas pressure is 3-5 lbs. for LP, or 1-2 lbs. for natural gas. (hi-lo units only)

20.Increase the cycle set point to return to high flame.(hi-lounitsonly)

21.Watch heater run several minutes to make sure it cycles between hi and lo flame or on and off properly.
